Abstract: To provide a method for manufacturing three-ply or four-ply tissue paper that reduces a sticky feeling of an outer surface while securing necessary softness. In manufacturing tissue paper including a stacked sheet in which three plies or four plies are stacked, each of the plies contains an aqueous moisturizer exhibiting hygroscopicity, and each of the plies has a difference in magnitude of an arithmetic mean height Sa according to ISO 25718 between both surfaces of each of the plies. A manufacturing method includes: applying the moisturizer to each of the plies such that the moisturizer is applied to an outer surface of each of the plies located on an outer side of the stacked sheet in a state where the outer surface has a small value of the arithmetic mean height Sa; folding the stacked sheet in which the moisturizer has been applied to each of the plies; and then storing the stacked sheet in the storage body in a folded state.

The bonded portions are arranged in continuous line shapes or dotted line shapes so as to form same-sized regular hexagons, which connect each other as unit shapes to be a honeycomb shape. All the cells are the same-sized regular hexagonal cells each of which is surrounded by the bonded portions.

The above-mentioned problem is solved by an absorbent article including an absorber having a plurality of cells surrounded by bonded portions of an upper sheet and a lower sheet, the upper sheet and the lower sheet not bonded at the cells, and a particulate material including super absorbent polymer particles contained in the cells, in which at least one of the upper sheet and the lower sheet in the cells is formed into concaves depressed to outsides of the cells in a spread state, a middle sheet made of a nonwoven fabric is interposed between the upper sheet and the lower sheet, and the middle sheet is compressed in a thickness direction at the bonded portions and expands to insides of the concaves at portions located inside the cells.

Abstract: A particulate material feeding device has a particulate material storage tank for storing particulate materials, a delivery device for continuously delivering the particulate materials stored in the particulate material storage tank, a chute which drops and transfers the particulate materials delivered from the delivery device to drop and feed the particulate materials to a feeding position, a blocking body which intermittently enters a blocking position for blocking at least a part of the particulate passage in a cross-sectional direction in the chute, from a non-blocking position, and a recovery path branched from the chute so as to discharge the particulate materials blocked by the blocking body to the outside of the chute.
